Question

I Science Sem 1

Answer 1

Answer:

Force, F = 124 N

Explanation:

We have,

Mass of bicycle is 12 kg and mass of rider is 50 kg

Total mass of the system is 12 kg + 50 kg = 62 kg

Acceleration of the system is 2 m/s²

It is required to find the force required to accelerate the system. The force acting on an object is given by :

$F=ma\\\\F=62\ kg\times 2\ m/s^2\\\\F=124\ N$

So, the force of 124 N is acting on the system.
